Novel thermotropic liquid crystalline poly(aryl ether ketone) was synthesiz
ed via the random copolycondensation of 4, 4'-difluorobenzophenone, 4,4'-bi
phenol and tert-butylhydroquinone, The results of differential scanning cal
orimetry, polarizing light microscope and X-ray diffraction confirmed the l
iquid crystalline property of the polymer, The polymer may be of great use
in blending with normal poly(aryl ether ketone)s.
